Description

Vibration removal tool

The present invention relates to a device for disassembling a fastener, and more particularly to a shock detaching tool.

Most of the general items are made up of various components. The way to connect the joints is that the fasteners are matched with the threaded parts to combine the locks. The fasteners are usually screws, bolts and nuts. . Understandably, when the item needs to be replaced and the part needs to be replaced, the fastener needs to be removed first. In order to ensure that the fastener can be loosely removed and the fastener is not damaged, a torque tool is usually used (such as Wrench) is fitted with a sleeve for disassembly work, such as the disassembly tool disclosed in TWI549783 and TWM534659.

However, in such a disassembly tool, during the operation of the rotation, only the torque is applied to the fastener to make it rotate, so when the fastener is rusted or other reasons, the fastener and the locked object are threaded. When an unintended combination occurs, the force must be applied with greater torque to force the fastener to rotate. At this point, the following situations will be encountered. One is that the user cannot provide enough torque to rotate the fastener, and the other is due to excessive torsion force and stress concentration, which causes partial collapse of the fastener, regardless of the above. It will have an adverse effect on the disassembly work, and there are defects that need to be improved.

Therefore, it is necessary to provide a novel and progressive vibration disassembly tool to solve the above problems.

The main object of the present invention is to provide a vibration disassembly tool which can provide a force other than the torsion force to the fastener through the impact vibration, thereby loosening the fastener and being easily rotated by the torque to ensure the disassembly operation. Smoothness.

To achieve the above object, the present invention provides a vibration disassembly tool including a body and a control assembly. The body is provided with an axial direction and includes a working end, a driving end and a joint portion disposed along the axial direction, the working end is for driving a fastener to rotate, and the driving end is provided by an impact source. The joint portion is disposed between the working end and the driving end. The control component is provided with a triggering member and a connecting component. The connecting component is coupled to the triggering member and the joint portion in the axial direction, thereby positioning the triggering member on the joint portion.
